VIEWFINDER AND FOGUSING
The perfect combination of Fresnel
Screen and Conde nsor Lens used in the
viewing system of PETRI FT is the result
of Petri's highly adva nced tech nical and
engineering ability. The precision focus-
ing elements in the viewing system con- @
sist of a group of m icro-lenses as shown
in the centre of the picture. As you look cthrough the micro-lens area @ in the
viewfinder you can see the subject clear- IN FOCUS
ly ON LY when it is correctly f ocused.
Rotating the focusing ring you will notice
the appearance of something like the
mesh of a net in the centre of the view-
finder. This reticulation is caused by the
flickering of reflected lieht entering the
camera lens. When the subject is correct-
ly focused the flickering grid fades away
from the micro-lens area. In the second
inner circle @ ttre subject is always seen
sharp and clear, even when the lens is
out of focus. When the lens is correctly
focused, the image in the micro-lens
area will be sharp and clear as that seen
in the surrounding circle@.
